Signs perimenopause is ending
There is one sign that actually means something, and it is a gap. A stretch of sixty days or more without a period marks late perimenopause, the last stage before your final one. Almost everything else listed as a sign is a symptom that can turn up at any stage, or something only visible in hindsight.

Check your stage
Four questions, about thirty seconds. It places you against the STRAW+10 criteria, the staging system clinicians use, and tells you which stage you are in and what is typically left. It runs entirely in your browser, and nothing you enter is stored or sent anywhere.
The one sign that actually means something
STRAW+10 marks the late menopausal transition, Stage -1, by the occurrence of amenorrhoea of sixty days or longer. In plain terms: you went two months or more without a period. That is the criterion, and it is the only widely agreed marker that you have moved into the last stage before your final period.
It is a low bar in one sense, since a single long gap meets it, and a high bar in another, since nothing else on the usual list of signs qualifies. The reason the criteria lean this hard on bleeding is deliberate: the workshop set out to use criteria independent of age, symptoms and pathology, because no universal menopausal syndrome has been established across ethnic groups. Symptoms vary too much between people to define a stage. Cycles do not.
Two other things characterise this stage. Hormone levels swing to extremes rather than settling, and cycles without ovulation become more common. That is the biological reason the late stage often feels less stable than the years before it, not more.
What is not a reliable sign
Search results for this question tend to list symptoms. Most of them cannot tell you where you are, because they occur across several stages or are only interpretable afterwards.
| Commonly listed as a sign | Why it does not place you |
|---|---|
| Worsening hot flushes | Vasomotor symptoms are likely during late transition, but they are most likely in the first two years after the final period. Intensity does not distinguish before from after. |
| Symptoms easing off | Can happen at any point. Hormone levels fluctuate rather than declining smoothly, so a quiet few months is not progress in a straight line. |
| Lighter or shorter periods | Flow changes occur across the whole transition, including the late reproductive stages before perimenopause has formally begun. |
| Your age | STRAW+10 recommends applying the criteria regardless of age, ethnicity, body size or lifestyle. Two people of the same age can be several stages apart. |
| Your mother's age at menopause | A weak population-level association at best. It is not a staging criterion and cannot date your own transition. |
| A hormone test result | FSH above 25 IU/L on a random draw is characteristic of late transition, but levels in this stage swing between menopausal and reproductive ranges, so one draw cannot settle it. |
None of these are meaningless. They are simply not stage markers, which is a different job from being a real symptom.
How long late perimenopause lasts
The late menopausal transition is estimated to last one to three years on average, based on studies of menstrual calendars and on changes in FSH and estradiol. That is the most specific honest answer available, and the variation around that average is wide.
After the final period, hormones keep moving. FSH continues rising and estradiol continues falling for roughly two years before both stabilise, which is why STRAW+10 splits early postmenopause into three substages. Vasomotor symptoms are most likely during the first two of them. Early postmenopause as a whole runs about five to eight years.
The thing nobody can give you is a date. Your final menstrual period is Stage 0, and it is identifiable only in retrospect, twelve months after it happens. You learn the date by counting backwards a year after the fact. Any tool or test claiming to predict it in advance is overselling what the staging system itself can do.
The twelve months that end it
Perimenopause does not end at your final period. STRAW+10 is explicit: perimenopause begins at Stage -2 and ends twelve months after the final menstrual period, which is the end of Stage +1a.
So the year of no periods is not the aftermath. It is the last stretch of the thing itself, and it is the stretch during which you cannot yet know whether it has finished. If a period arrives in month eleven, the count restarts and you are still in the late transition. That is not a setback in any medical sense, though it rarely feels neutral.
This also answers a question people ask in the wrong order. You do not find out that perimenopause is ending. You find out, twelve months later, that it ended.
What the late stage tends to feel like
Because hormone levels fluctuate to extremes in this stage rather than declining gently, the late transition is frequently the least predictable part. Common descriptions include hot flushes and night sweats arriving without their old pattern, sleep breaking up, mood and anxiety swinging with no obvious trigger, and cycles that skip and then return heavier.
It is worth scoring the whole picture rather than tracking one symptom, because the pattern across domains is what a clinician can act on. Our check weights sixteen symptoms across four domains and stages your cycle at the same time, and prints a summary you can hand over. If you want the staging system itself, every STRAW+10 stage is written out here.
Bleeding that needs a clinician, not a tool
This stage is exactly where the important bleeding rules apply, so they are worth stating plainly rather than burying.
- Any bleeding after twelve months with no periodThis is postmenopausal bleeding and needs in-person assessment. It is often something benign, and it is investigated promptly regardless. Do not wait to see whether it happens again.
- Bleeding that is unusually heavySoaking through protection hourly, passing large clots, or bleeding that stops you doing normal things. Heavy bleeding is common in this stage and still worth assessing, not least because it causes iron deficiency.
- Bleeding that lasts longer than usual, or between periodsIncluding bleeding after sex. A change in pattern is the thing being assessed, not the amount alone.
- Periods returning after a long gap, repeatedlyWorth mentioning rather than assuming it is just the transition being erratic, particularly if the returning bleeds are heavy.

Common questions
What are the signs perimenopause is ending?
One sign carries real weight: a gap of sixty days or more without a period, which is the STRAW+10 criterion for late menopausal transition, the last stage before your final period. Most other commonly listed signs, including worsening or easing symptoms, lighter periods and your age, occur across several stages and cannot place you.
How do you know when perimenopause is over?
Twelve months after your final menstrual period, and you can only know it in retrospect. STRAW+10 defines perimenopause as beginning at Stage -2 and ending twelve months after the final period. If a period arrives during that year, the count restarts. Nobody knows their final period was the final one at the time.
How long does late perimenopause last?
One to three years on average, based on menstrual calendar studies and on changes in FSH and estradiol. That average conceals wide individual variation. After the final period, hormones keep moving for roughly two more years before stabilising, and early postmenopause as a whole runs about five to eight years.
What are the symptoms of late perimenopause?
Hormone levels swing to extremes in this stage rather than declining gently, and cycles without ovulation become more common, so unpredictability is the theme. Hot flushes and night sweats losing their pattern, broken sleep, mood and anxiety swinging without a trigger, and skipped periods returning heavier are all common. Vasomotor symptoms are likely here and most likely in the two years after the final period.
Can you tell when your last period will be?
No, and no test can. The final menstrual period is Stage 0 in the staging system and is identifiable only twelve months afterwards, by counting backwards. Hormone levels in the late transition swing between menopausal and reproductive ranges, so a blood draw cannot date it either.
Do symptoms get worse before perimenopause ends?
Often, though not as a rule. The late transition carries extreme hormonal fluctuation, and vasomotor symptoms are likely during it and most likely in the first two years after the final period. So the heaviest stretch commonly straddles the end rather than stopping at it, which is not what most people expect.
I bled after a year with no periods. Is that normal?
It needs in-person assessment, promptly. Any bleeding after twelve months without a period is postmenopausal bleeding, and it is investigated regardless of how light it is or how well you feel. It is frequently caused by something benign. That is a reason to have it checked rather than a reason to wait.
Score the whole picture
A stage tells you where you are. It does not tell you how much you are carrying. The check scores sixteen symptoms across four domains alongside the staging, and prints a summary in the language a clinician recognises.
You find out it ended a year after it did. That is not your fault, and it is not a failure of attention.
